C语言实现一个动态链表

代码：

#include <stdio.h>
#include <malloc.h>
struct weapon {
  int price;
  int atk;
  struct weapon * next;
};
struct weapon * create() {
  struct weapon * head;
  struct weapon * p1, * p2;
  int n = 0;//记录节点个数
  p1 = p2 = (struct weapon*)malloc(sizeof(struct weapon));
  scanf("%d,%d", &p1->price, &p1->atk);
  head = NULL;
  while(p1->price != 0) {
    n++;
    if(n == 1) {
      head = p1;
    } else {
      p2->next = p1;
    }

    p2 = p1;
    p1 = (struct weapon*) malloc(sizeof(struct weapon));
    scanf("%d,%d", &p1->price, &p1->atk);
  }
  p2->next = NULL;
  return (head);
}
int main() {
  struct weapon *p;
  p = create();
  printf("%d,%d", p->price, p->atk);
  return 0;
}
